Improvement in casting bar-solder



ABRAHAM SCHOENBERG, OF NEW YORK, N. Y.

IMPROVEMENT IN CASTING BAR-SOLDER.

Specification forming part of Letters Patent No. 110,684, dated January 3, 1871.

To all whom fit may concern Be it known that I, ABRAHAM SCHOEN- BERG, of the city, county, and State of New York, have invented, made, and applied to use a new and useful Machine for (lasting Bar- Lead, Bar-Solder, vVireMetal, and Printers Leads; and that the following is a full, clear, and correct description of the same, reference being had to the accompanying drawing, making part of this specification, and to the letters of reference marked thereon, in which- Figure l is a side elevation of my improved machine. Fig. 2 is a top view ofthe saine. Fig. 3 is an end view of the saine.

In the drawing like parts of the invention are pointed out by the same letters of reference.

The nature of the presentinvention consists in the construction, as more fully hereinafter set forth, of a new and improved machine for casting bar-lead, bar-solder, wire-metal, and printers7 leads, the object of the invention being the production of a machine by which barlead, bar-solder, wiremetal, and printers7 leads, of any desired length and thickness, can be made expeditiously and more economically than by the present mode.

To enable those skilled in the arts to make and use my invention, will describe the same.

A shows the frame of the machine, which may be made of any suitable material, and serves to support the operative parts of the machine. The frame A is slotted to receive the adjustable boxes B, in whichthe shattCis held, and which boxes may be adjusted by means of the regulating-screws D, inserted in the frame A, and having their bearings against the rear ends of the boxes B. Upon this shaft Gis keyed a cog-wheel, E, gearing into the Cog-wheel F, secured upon the shaft G, and also into the pinion VH, secured upon the shaft I. J shows a grooved wheel secured upon the sha-ft C.

G is a shaft secured in the frame A, having keyed upon it the cog-wheel F, gearing into the cog-wheel E, and also into the pinion J2,

held upon a shaft, K. L shows a ribbed wheel secured upon the shaft G, thefrrib'upon which wheel is made to tit the groove in the wheel J.

Upon the shaft K, held in theframe A, are the fast and loose pulleys M and N, by which the machine may be connected with any suitable motor.

I shows a shaft secured in the frame A, having secured upon it the pinion H, gearinginto the cog-wheel E, and also into the pinion O, keyed upon a shaft, P, which shaft'also supports a second grooved wheel, P2. This shaft P is held in adjustable boxes a, inserted in the slotted portions of the frame A, the position 'and having keyed upon its opposite end the pinion U, gearing into the pinion O upon the` shaft P.

The ribbed wheel S has secured upon its face a knife, V, and the grooved wheel P2 is slotted upon its face to receive the knife V.

I shows a hopper, made V-shaped, and supported by the supports 2, which hopper, when in position, is placed directly Vbetween the ribbed and grooved wheels, and is provided with an aperture upon the grooved-wheel side to allow the molten metal to pass from the hopper into the groove in the wheel.

The hopper may be supplied with molten metal from a kettle or heater connected with the hopper, in any convenient way.

3 shows a rod held in the frame A, and hav ing upon one end the weighted lever 4, and also a scraper, 5, which scraper is so positioned that it shall fall in line with the groove in the grooved wheel. 6 shows a rod hung in the frame A, directly in front of the grooved wheel` P2, and having upon it the weighted lever 7 and scraper 8, which scraper is so positioned upon the rod as to have a bearin g in the groove upon the wheel P2.

Such being the= construction, the operation may be thus set forth The wheels J, L, P2, and S are first adjusted to each other so as to give the thickness desired for the bar or lead by means of the regulating-screws D and K, and connection is established between the hopper the face of the wheel I. From these nishing-wheels the metal is relieved by means of the scraper 8, operating as already described in the ease of the scraper 5.

When wire-metal is to be made upon. the machine, the groove and rib upon the wheels are made halfround, and the wire-metal will be formed by the machine, as already described in the case ot' bar-lead, bar-solder, or printers7 leads.

Having thus described my invention, what I claim as new is- 1. In combination with ahopper, 1, constructed substantially as described, the grooved and ribbed wheels J and L and scraper 5, when the same shall be constructed and operate substantially as and for the purpose set forth.

2. In combination with the finishing-wheels l?2 and S, knife V, and scraper 8, the hopper 1, grooved and ribbed wheels J and L, and scraper 5, when the same shall be constructed substantially as and for the purposes set forth.

and a metal kettle, so that the hopper will be supplied with molten metal. The scrapers 5 and 8 are elevated by throwing back the weighted levers 4 and 7 so that they have a bea-rin g upon the grooved wheels J and P2, the w ei ghted levers counterb ala-nein g the scrap ers, and being sufciently heavy to hold them well up to their work. Power may now be applied to the machine, and, through the pulleys and gearing already described, causes the grooved and ribbed wheels to revolve. rEhe molten metal to be formed into bars or leads issues from the hopper through the aperture in the same, and into the groove upon the wheel J, where it is pressedinto strips by the rib iitting into this groove. As the wheels continue to revolve the pressed metal is brought into contact with the forward end of the scraper 5, which, entering between the groove and the rib, flattens out, so to speak, the pressed metal, and relieves it from the grooved wheel, whence it s fed along to the finishing-wheels P2 and S, where it is finished by passing through the same, and where, also, the operation of cutting is accomplished by the knife V, which passes through the inetzl and enters the slot upon
